From cf9610f9116d55c5a66ef9f1faecacabd93a9322 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 24 Aug 2026 08:46:03 -0700 Subject: Merge tag 'pinctrl-v7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "Core changes: - Use the non-blocking mux_state_try_select() in the generic MUX pin control back-end - Free pin maps on pinctrl_generic_to_map() failure in the core helpers New hardware pin control: - Qualcomm Maili TLMM SoC, PMG1110 PMIC, and Eliza LPASS LPI TLMM SoC (this is for the low power audio, LPASS = Low Power Audio SubSystem portions) - Upboard support on top of the Intel pin controller - Apple T6030 and T6031 support (just compatible strings) - Samsung Exynos 8855 SoC - Mediatek MT6858 SoC - Rockchip RK3308B and RV1106 SoCs - Airoha EN7523 and AN7563 SoCs Improvements: - Qualcomm TLMM GPIOs are unconditionally marked as wakeup capable - Qualcomm improvements on top of the Qualcomm PDC (power domain controller) irqchip improvements from tglx:s tree - Qualcomm IPQ806x and IPQ9650 non-urgent pin grop fixups - The NPCM8xx driver has been put into shape fixing many pin and group definitions - Some non-urgent Tegra 264 pin assignments are fixed up - Some non-urgent fixups to Airoha AN7581 and AN7583 registers and pin assignments, missing features etc" * tag 'pinctrl-v7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (130 commits) dt-bindings: pinctrl: Convert TI DA850 pupd to DT schema pinctrl: meson: sync some modify from A4 pinctrl: meson: a4: Add input enable pin configuration pinctrl: realtek: rtd1625: remove unused group name spdif_sel pinctrl: realtek: rtd1625: fix base_bit for VE4 GPIO 13 dt-bindings: pinctrl: microchip,pic32mzda-pinctrl: Convert to DT schema Revert "Merge branch 'ib-rsk7204' into devel" pinctrl: rockchip: Add RV1106 pinctrl support dt-bindings: pinctrl: rockchip: Add RV1106 compatible pinctrl: rockchip: Decode drive strength in the get function pinctrl: fix PINCTRL_GENERIC_MUX not always being selectable pinctrl: airoha: add support of an7563 SoC dt-bindings: pinctrl: airoha: add support of an7563 pin controller pinctrl: airoha: try to find chip scu node by phandle first pinctrl: airoha: add support of en7523 SoC dt-bindings: pinctrl: airoha: add support of en7523 pin controller pinctrl: airoha: an7583: add support for olt pinmux pinctrl: airoha: an7583: add support for pon_alt pinmux pinctrl: airoha: an7583: add support for npu_uart pinmux dt-bindings: pinctrl: airoha: an7583: add missed features ... --- arch/sh/lib/io.c | 79 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 79 insertions(+) create mode 100644 arch/sh/lib/io.c (limited to 'arch/sh/lib/io.c') diff --git a/arch/sh/lib/io.c b/arch/sh/lib/io.c new file mode 100644 index 000000000..dc6345e4c --- /dev/null +++ b/arch/sh/lib/io.c @@ -0,0 +1,79 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * arch/sh/lib/io.c - SH32 optimized I/O routines + * + * Copyright (C) 2000 Stuart Menefy + * Copyright (C) 2005 Paul Mundt + * + * Provide real functions which expand to whatever the header file defined. + * Also definitions of machine independent IO functions. + */ +#include +#include + +void __raw_readsl(const volatile void __iomem *addr, void *datap, int len) +{ + u32 *data; + + for (data = datap; (len != 0) && (((u32)data & 0x1f) != 0); len--) + *data++ = __raw_readl(addr); + + if (likely(len >= (0x20 >> 2))) { + int tmp2, tmp3, tmp4, tmp5, tmp6; + + __asm__ __volatile__( + "1: \n\t" + "mov.l @%7, r0 \n\t" + "mov.l @%7, %2 \n\t" +#ifdef CONFIG_CPU_SH4 + "movca.l r0, @%0 \n\t" +#else + "mov.l r0, @%0 \n\t" +#endif + "mov.l @%7, %3 \n\t" + "mov.l @%7, %4 \n\t" + "mov.l @%7, %5 \n\t" + "mov.l @%7, %6 \n\t" + "mov.l @%7, r7 \n\t" + "mov.l @%7, r0 \n\t" + "mov.l %2, @(0x04,%0) \n\t" + "mov #0x20>>2, %2 \n\t" + "mov.l %3, @(0x08,%0) \n\t" + "sub %2, %1 \n\t" + "mov.l %4, @(0x0c,%0) \n\t" + "cmp/hi %1, %2 !
